Other observations of Grass Snake (Natrix natrix)

Comments

in the UK are usually grass snakes, which hunt for small fish and amphibians.
Adders will swim, but only to get to where they want to be: say if there is a stream between the hibernaculum and the pretty girls.

Do you get grass snakes where you are? In Yorkshire they are missing north of a line running west roughly from Hull, through York and Leeds. I know they re-appear around the Scottish borders but wondered if you had any pockets in Northumberland / Teeside. For example, we have none in Ryedale or the NY Moors.

seen on Teesside in my few years here. I think we're too far north, and of course a lot of the "fresh" water is saline due to minewater or tidal influence.
I have seen "pockets" of them further north on the distribution maps. This is probably due to local "microclimate" effects, I'd guess.
I used to see them in Worcestershire, but being nomadic, they were harder to find than adders.
